Compatible HD Export for Western Digital Live Hub

Need to Export 720 x1280 HDV Clips for Large Format (Life Size) Signage. Just purchased WD TV Live Hub which I thought would work well as an HD Digital player connected via HDMI to an HD projector. Was working in Pro Res for highest quality but WDTV says incompatible. Have tried numerous compressor settings with no luck - except MPEG4 (which did wok but the quality was way to low.). Need High quality life size image. Western Digital says quicktime, AVC and .mov are compatible. Anybody know a compressor setting that will work and still give me the 720 x 1280 HD quality I need?

If not, does anyone know of a digital player that will output quicktime HD files? Thanks so much.
